摘要:
A receiving part for coupling a bone anchor to a rod is provided, where the bone anchor includes a shank for anchoring to a bone or a vertebra. The receiving part includes a first end and a second end, the second end being connected to the shank, a bore extending from the first end into the receiving part for receiving a fixation device, the bore having a bore axis, and a recess for receiving a rod, the recess being open at the first end of the receiving part for allowing insertion of the rod and having opposing sidewalls on at least one side of the bore. When a rod is inserted into the recess, a longitudinal axis of the rod extends substantially perpendicular to the bore axis. A resilient retention element is provided on at least one of the opposing sidewalls, where the resilient retention element is deflectable toward the at least one sidewall when the rod is inserted.
